Microdata access conditions
General conditions

Researchers affiliated with pre-approved Danish research institutions can be granted authorisation to access register data, collected from the 1970s to the present. Access is given to data at personal level (individual persons or firms) for several years, albeit stripped of direct identifiers. Access is given on the basis of a need-to-know principle. Users can be authorised to link register data with data from other sources, such as surveys.

Conditions for non-resident researchers

Non-resident researchers can get access to microdata through an affiliation to a Danish pre-approved research institution, which takes responsibility for use. What matters is affiliation (that is, the institution that takes responsibility and can be sued in case of breach) rather than physical location of the user (indeed authorised Danish researchers can connect to the system from abroad).

Requests should be addressed to the Division of Research Services [Click Here]. They should be accompanied by a detailed research project justifying the need for the microdata requested. Authorisation requires signature of an agreement between Statistics Denmark, the user, and a representative of their institution.
If access is granted, it takes place through researcher’s own computer over the internet, using a secure remote access system (in place since 2001), where the researcher works with the data without being able to export it, and outputs are systematically checked for statistical disclosure before release.

Details & practical information
How much does it cost?

Access is free of charge unless the user wishes to link register data to a customised survey. When the design of a particular survey is settled, Statistics Denmark provides a final price quote.
